BOLT-MAKING DEVICE.

SPECIFICATION forming part of Letters Patent No. 311,083, dated January 20, 1885.

Application filed March 26, 1884. (No model.)

' :0 (LE whom zr may concern:

Be it known that I, ELAM A. OLIVER, of Belleville, county of Dane and State of \Visconsin, have invented a new and useful Improvement in Vises and Shears; and I do here by declare that the following is a full, clear, and exact description of the invention, which will enable others skilled in the art to which it appertains, to make and use it, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to improvements in mechanics vises in which a vise and shears operate in conjunction; and the objects of my invention are, first, to obtain a perfect closure of the jaws of the vise; second, to provide cutting apparatus to operate in unison with the vise; third, to magnify the power exerted to close the jaws of the vise; and, fourth,to obtain compactness of form. I attain these objects by the means showninthe accompanying drawings, in whicl1- Figurel is a side elevation of my invention ready for use. Fig. 2 is a plan view of my invention when in use. Fig. 3 is a front elevation of Fig. 1. Fig. 4 is a detail of shears and guide.

The device is formed with one stationary limb, N, fixed to the floor or other part by the foot 0 and braces I? I, as shown, and a piv oted limb, H, secured by the pivot J to bracket T, which is formed or fixed upon the stationary limb N. Each of the limbs carries a jaw, the one upon limb N being marked M, and that upon limb H being marked K. Each limb also carries a shearbladeon one side, as shown, that upon limb N being marked R, and that upon limbHbeing marked R. The limb H is operated, by mechanism hereinafter explained, to approach and recede from limb N at the top, so as to clo'se and open the jaws and blades.

Upon the stationary limb N is secured an arm, S, which projects toward the limb H on the side opposite tothe shear-blades,and serves to prevent the metal being cut from twisting,

, said metal to be out being placed between the limb N and the arm S, between the shearblades, as may readily be understood from Fig. 1. The lower end of the arm S is turned outward toward the limb H to form a guide, S, therefor. This guide S,lying snugly up against the limb H, serves to keep it from twisting or moving upon its pivot J to any great or hurtful degree. The pivoted limb H is provided with the longitudinal slot G, and is operated by the following mechanism: A curved foot-lever, A, is fulcruined on thepivot B to the parts D D, and has a flange or flanges, G, which rest under the parts D, below the pivot B, and afford a means for engaging the lever A and parts D rigidly when the lever is depressed, and at the same time allow the le ver A to be elevated by being turned upward on its pivot B, when desired. The parts D are fnlcrumed upon the pivot E, supported by limb N. At their lower ends the parts D are provided with a friction-roller, F, which works in the slot G in the limb H. Now, it is evident that as lever A is depressed the lower end of the pivoted limb H will be forced away from the limb N, and the jaw K and blade R thrown toward jaw M and blade R, and that they remain so as long as power is applied to lever A. If the weight of the limb H below the pivot J, united with that of the parts D below the pivot E, exceed that of these parts D H above said pivots united with that of lever A, the jaw K will be automatically thrown back or opened when the power is removed from lever A; but as this would un necessarily increase the weight and cost of these parts an automatic means is provided for opening the jaws when the power is removed from the lever A. This consists of a spring, I, wound round pivot E, and secured at one end to a brace, P, and having an out wardextending limb or end which engages with a loop, F extending out from the roller E. The force of this spring tends to keep the jaws open, and although readily overcome when power is applied to the lever A, yet itsforce is sufficient to make the opening of the jaws decided and immediate when the power is removed from lever A. The jaws K and M are provided with grooves LL, which match each other in the two jaws, and form circular openings between them for holding circular objects.

My invention is designed, principally, for the manufacture of bolts, to do which the opera tion is as follows: The iron bars are cut in lengths longer than is requisite by means of the shears RR. These cut bars are taken and bar.

put into thegrooves L Lin the vise hot-,where l N and H, having the jaws K and M and the they are held firmly and then headed. In the cutting the bar is kept from twisting by the guide S, which forms an acute angle with the inner side of the arm N, the opening of the angle being at the top, thus holding any-sized WVhen the foot is raised off the lever A, the spring I, by means of its engagement with the loop F, forces the lever D down, and the lower part of the arm H in, thereby opening thejaws of the vise. The lever A is jointed to the parts D in order that when not in use it maybe thrown up out of the way, as shown in dotted lines in Fig. 1.

Of conrse'I' do not confine myself to the manufacture of bolts, but claim all the purposes for which it may be used.

Having thus fully described my invention, what I claim, and desire to secure by Letters Patent of the United States, is

1. The combination, with the stationary limb N and pivoted limb H, of the parts D, connected with thelimb H, as described, and the lever A, pivoted to parts D, and provided with the locking-flange G, as set forth.

2. The combination, with the upright limbs which the roller F works, and the jaws K and M, substantially as set forth.

7 4. The combination, with the levers A and D,.fiXC-(l limb N, and the pivoted limb H, of the spring I and jaws K and M, said spring being secured to a fixed part at one end and to the pivot of parts D and H at the other, as set forth.

In testimony that I claim the foregoing I append my signature.

ELAM A. OLIVER.
